TAB. 20 – Profibus connections
On the card there is a double dip switch referred to as DS1 that, if closed, connects the signal CAN H and CAN L by
means of a 120 Ω resistor for the line termination.
 CAN H and CAN L terminated by 120 Ω
resistor
 CAN H and CAN L not terminated by resistor
Default setting: CAN H and CAN L
signals terminated on 120 Ω resistor.
ANY OPERATION MUST BE MADE ONLY WITH CONVERTER NOT POWERED.
